Products of nuclear fission, including Barium and Krypton.

Atoms formed from the fission of nuclear materials that can capture neutrons.

Fuel where less than 1% of fissionable nuclei remains, suitable for reprocessing.

Measure of how much energy a fuel mass can produce, expressed as MW-day/ton.

Neutrons released during fission necessary for sustaining chain reactions.

Minimum core size required to maintain a chain reaction of neutrons.

Amount of nuclear fuel required to maintain a self-sustaining chain reaction.

When fission neutrons escape the core, reducing efficiency of the reaction.

Substances that slow down neutrons to increase fission efficiency, like water or graphite.

Reactors that use thermalized slow neutrons for fission.

Fast neutrons (> 10 keV) have advantages in fission processes.

Natural uranium contains 0.005% U-234, 0.7% U-235, and 99.3% U-238.
